Challenges in planet formation

A Morbidelli, SN Raymond - Journal of Geophysical Research …, 2016 - Wiley Online Library
Over the past two decades, large strides have been made in the field of planet formation. Yet
fundamental questions remain. Here we review our state of understanding of five …

M stars as targets for terrestrial exoplanet searches and biosignature detection

J Scalo, L Kaltenegger, A Segura, M Fridlund, I Ribas… - Astrobiology, 2007 - liebertpub.com
The changing view of planets orbiting low mass stars, M stars, as potentially hospitable
worlds for life and its remote detection was motivated by several factors, including the …

Planet formation theory in the era of ALMA and Kepler: from pebbles to exoplanets

J Drazkowska, B Bitsch, M Lambrechts… - arXiv preprint arXiv …, 2022 - arxiv.org
Our understanding of planet formation has been rapidly evolving in recent years. The
classical planet formation theory, developed when the only known planetary system was our …

Origin of water in the inner Solar System: Planetesimals scattered inward during Jupiter and Saturn's rapid gas accretion

SN Raymond, A Izidoro - Icarus, 2017 - Elsevier
There is a long-standing debate regarding the origin of the terrestrial planets' water as well
as the hydrated C-type asteroids. Here we show that the inner Solar System's water is a …

A Emsenhuber, C Mordasini, R Burn, Y Alibert… - Astronomy & …, 2021 - aanda.org
Context. The explosion of observational data on exoplanets gives many constraints on
theoretical models of planet formation and evolution. Observational data probe very large …

How drifting and evaporating pebbles shape giant planets-I. Heavy element content and atmospheric C/O

AD Schneider, B Bitsch - Astronomy & Astrophysics, 2021 - aanda.org
Recent observations of extrasolar gas giants suggest super-stellar C/O ratios in planetary
atmospheres, while interior models of observed extrasolar giant planets additionally suggest …

Three-dimensional interaction between a planet and an isothermal gaseous disk. I. Corotation and Lindblad torques and planet migration

H Tanaka, T Takeuchi, WR Ward - The Astrophysical Journal, 2002 - iopscience.iop.org
Gravitational interaction between a planet and a three-dimensional isothermal gaseous disk
is studied. In the present paper we mainly examine the torque on a planet and the resultant …

Toward a deterministic model of planetary formation. I. A desert in the mass and semimajor axis distributions of extrasolar planets

S Ida, DNC Lin - The Astrophysical Journal, 2004 - iopscience.iop.org
In an attempt to develop a deterministic theory for planet formation, we examine the
accretion of cores of giant planets from planetesimals, gas accretion onto the cores, and …

The mass of gas giant planets: Is Saturn a failed gas giant?

R Helled - Astronomy & Astrophysics, 2023 - aanda.org
The formation history of giant planets inside and outside the Solar System remains
unknown. We suggest that runaway gas accretion is initiated only at a mass of∼ 100 M⊕ …

Formation of planetary systems by pebble accretion and migration: growth of gas giants

B Bitsch, A Izidoro, A Johansen, SN Raymond… - Astronomy & …, 2019 - aanda.org
Giant planets migrate though the protoplanetary disc as they grow their solid core and attract
their gaseous envelope. Previously, we have studied the growth and migration of an isolated …
